How do I wire it to the pcb? Where is the ground on the LM386 for the on/off switch??I did a continuity test and and the rocker switch doesn't break the circuit I still have tone even when the switch is on the off position.

Leave the circuit as is, just leave the slide switch on. Wire the rocker switch in line with the power supply. I'm not sure how the light in the rocker switch is wired, you might be able to remove the LED and wire the switch LED in place.

I want to use it in a project box so I can actually use the amp and the switch that comes with it is rectangular and cannot cut it out plus it's way too small here's the switch that I want to use. http://www.nfauto.co.uk/images/feb2007/mini_rocker_led.jpg It has a + , A , GROUND symbols on the body for the 3 leads. What does the A means? I would assume that the + gets connected to the positive pole of the 9v and the ground to the ground of the kit, but not sure about the A lead.

Do you know how to wire it to that kit??? There's 3 really small holes in the PCB top is OFF and bottom is ON with a white square that covers the 2 bottom holes.

I believe it's the lead with the A on it

I will try (where it says ON on the PCB) to the + of the switch- the other ON position to the A (which I think is the LED in the switch) and the OFF position to the ground of the switch. Is that make sense???

BTW what is the best way to solder wire to a PCB??? I went from underneath by putting the point of the iron on both the pad and the wire itself and putting solder all the way around (got that from youtube videos) but the top where the drawing is, all the connectors have no strain-relief and are all getting loose and wobbly.

Just as a FYI I am taking an online electronic course and learning electronics with small projects as I take my course.

You have to handle any board with wires coming off with some delicacy, this is pretty much true of everything in this class. The real problem is rigidity, if you put too much solder into the wire it can't flex, so it will break. You DON'T want solder anchoring the wire too tightly, just enough for good electrical contact. Try not to flex the wires excessively. Plan what you are going to do, then do it with a minimum of fuss. Oh yeah, use stranded wire too.
